Castor oil comes from Ricinus communis (castor plants; Fig: sprig, panicle, seed); it is obtained from the first cold-pressing of the seed (shown in natural size). Oral administration of 10-30 mL of castor oil is followed within 0.5 to 3 h by discharge of a watery stool. Ricinoleic acid, but not the oil itself, is active. It arises as a result of the regular processes involved in fat digestion: the duodenal mucosa releases the enterohormone cholecystokinin/pancreozymin into the blood. The hormone elicits contraction of the gallbladder and discharge of bile acids via the bile duct, as well as release of lipase from the pancreas (intestinal peristalsis is also stimulated). Because of its massive effect, castor oil is hardly suitable for the treatment of ordinary constipation. It can be employed after oral ingestion of a toxin in order to hasten elimination and to reduce absorption of toxin from the gut. Castor oil is not indicated after the ingestion of lipo-philic toxins likely to depend on bile acids for their absorption.
